If there are 12 months in one year, and a decade is 10 years. Then there are 120 months in a decade. (12x10=120)
If one year has 12 months, then a decade would have 120. And two decades would be the double of that, so 240
840 months
480 months
300 months
0.042
1 year = 12 months 1 decade = 10 years = 10*12 = 120 months 10 decades = 10*120 = 1200 months
480. 12 Months a year X 10 Years in a decade = 120 Months 120 Months per decade X 4 Decades= 480 Months
5 decades would be 50 years. Multiply 50 and 12 for months. Your answer would be that there are 600 months in 5 decades.
5 decades = 50 years = 600 months
100 decades are in one thousand years.
Ten decades is one century.
There are 600 months in 5 decades. A decade is 10 years. A year is 12 months. 5 x 10 x 12 = 600
